We have recently managed to manipulate magnetically levitated micromagnets using a superconducting trap, demonstrating their unique potential as mechanical systems with even lower dissipation. In particular, we have proposed several original schemes for ultrasensitive measurements, which include tests of collapse models, the observation of Larmor precession in a macroscopic magnet and the realization of magnetometers and torque sensors with unprecedented resolution. In Trento we will develop a levitation platform based on hard micromagnets floated in superconducting traps in the Meissner state. We aim at demonstrating the potential of these systems as ultrasensitive magnetometers with sensitivity well beyond the Energy Resolution Limit and exploring the interplay between precessional and librational dynamics. Furthermore, we plan to perform fifth-force measurements, aiming at exploring the parameter space of exotic spin-spin interaction models.
